TMA - Temperature Transmitter

Brand: KOBOLD Instruments, Inc

The KOBOLD TMA temperature transmitter employs a Pt100 Class B resistive temperature detector (RTD) combined with an integrated, loop-powered 4-20 mA output transmitter.

Our optional digital indicator, Model AUF, plugs directly to the Hirschmann (DIN 43650) plug.

This sensor is rugged, and wetted materials are of 316 stainless steel construction. 1/4" and 1/2" NPT process fittings are available as a welded or adjustable compression design.

The compression fitting allows for an easy, one-time adjustment of the desired immersion depth.

The transmitter is factory-calibrated to the customer’s temperature requirements.

Recalibration via zero and span potentiometers located at the connector is possible.
